SHEET-MUSIC TURNER.

Specification of Letters Patent.

Patented July 24, 1917.

Application filed August 14, 1916. Serial No. 114,668.

T 0 all whom it may concern:

Be it known that I, JOHN J. SoHN, a citizen of the United States, residing at Roseville, in the county of Placer, State of California, have invented certain new and useful Improvements in SheetMusic Turners; and I do declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this application.

This invention relates to improvements in a device for the turning of music leaves or sheets used in connection with musical instruments. The object of the invention is to produce a structure for turning individual leaves or sheets which can be readily operated by a simple movement of the hand and which will turn but one sheet at a time in an accurate and eflicient manner, thus avoiding the annoyance of mistakes occasioned by the manual turning of the said leaves or sheets as is now the common prac tice.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purposes for which it is designed.

These objects I accomplish by means of such structure and relative arrangement of the parts as will fully appear by a perusal of the following specification and claim.

In the drawings similar characters of reference indicate corresponding parts in the several views.

Figure 1 is a top plan view of the music turner showing the casing broken out in section.

Fig. 2 is a front elevation of the music turner.

Fig. 3 is an end view showing a music sheet clamp and finger arm.

Referring now more particularly to the characters of reference on the drawings the numeral 1 indicates the music book or sheet back against the rack or music book. This wire may be fastened to the top of the rack as shown at the numeral 5.

To turn the sheets of the book or folio I have provided the following mechanism:

Disposed at a convenient place upon the front and to one side of the rack are a number of small hand wheels 6. 7, and 8, each of which is mounted upon the shafts 9, 10 and 11 respectively. Upon the inner end of such shafts 9. 10 and 11 are fastened bevel gears 12. 13 and 14. engaging similar bevel gears 15, 16 and 17 fastened upon the shafts 18, 19 and 20 disposed at right angles to the shafts 9. 10 and 11.

Fa stened upon the outer ends of the shafts 18, 19 and 20 are bevel gears 21, 22 and 23 meshing into similar bevel gears 24, 25 and 26 mounted upon the lower ends of vertical shafts 27, 28 and 29. These vertical shafts 27, 28 and 29 extend to the top of the casing 2 and above the rack 1 and have fastened thereon arms 30, 31 and 32.

The vertical shaft 29 projects slightly above the adjacent shaft 28 and the shaft 28 projects slightly above the shaft 27. The arms 30, 31 and 32 being fastened on the ends of such shafts 27. 28 and 29 are thereby permitted to clear each other when it is desired to swing them from side to side. For the same reason, I have made each of the arms 31 and 32 slightly larger than its adjacent arm.

Slidably fastened upon the end of each of such arms 30, 31 and 32 I have provided arms 33, 34 and 35 projecting at right angles thereto and then bent downwardly as at 36, 37 and 38 and having fastened on the ends thereof clamps 39, 40 and 41 respectively for engaging the sheets of music 42. These arms 33, 34. and 35 may be adjusted for the height of the sheet and positioned upon the arms 30. 31 and 32 to accommodate the width of the sheet of music being used.

To turn a sheet of music it will only be necessary to attach one of the aforementioned clamps thereto and then operate one of the hand wheels upon the front of the rack which will move the above described mechanism to swing one of the arms in the direction desired.

To swing the arm 30 to the right it will be necessary to operate the hand wheel 6 which will revolve the shaft 9, the bevel gear 12 meshing With the bevel gear 15, and the shaft 18 with the bevel gear 21 meshing into the bevel gear 26 mounted upon the vertical shaft 27; This shaft 27 when turned Will cause the arm 30 to swing in either direction as desired and Will carry the sheet of music to the left or right. The operation of the other arms 31 and 32 Will be the same.

From the foregoing description it Will readily be seen that I have produced such a device as substantially fulfils the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention as defined by the appended claim.

Having thus described my invention What I claim as new and useful and desire to secure by Letters Patent is:

A music sheet turner comprising a sup port, a horizontal shaft journaled in the support, a hand Wheel on one end of the shaft for turning the same, a beveled gear on the opposite end of the shaft, another shaft disposed horizontally at right angles to the first named shaft, a beveled gear on one end of the second named shaft engaging the first named beveled gear, another beveled gear on the opposite end of said second named shaft, a vertical shaft, a beveled gear on the lower end of said vertical shaft engaging said last named beveled gear, a projecting arm on the opposite end of the vertical shaft, and a means on the arm for engaging the sheet.

In testimony "whereof I affiX my signature.

JOHN J. SOHN.
